More isn't always better: Too much calcium has risks. Dietary calcium is generally safe, but more isn't necessarily better, and excessive calcium doesn't provide extra bone protection. If you take calcium supplements and eat calcium-fortified foods, you may be getting more calcium than you realize.
Genetic Recombination in Bacteria. This is a process where genetic materials, contained in two separate genomes, are brought together within one unit. In bacteria the recombination takes place by (1) transformation, (2) transduction and (3) conjugation.
Methods for hemoglobinometry can be grouped into 4 main classes depending on the basic technique employed with variants within each class: 1. Colorimetric Methods. 2. Gasometric Methods. 3. Specific Gravity Methods. 4. Chemical Methods. The method of choice for hemoglobin determination is the cyanmethemoglobin method (This is a type of colorimetric method). The principle of this method is that when blood is mixed with a solution containing potassium ferricyanide and potassium cyanide, the potassium ferricyanide oxidizes iron to form methemoglobin.
